Bill C-287: Housing Cost Transparency Act

This bill primarily affects homebuilders, residential developers, and construction contractors across all provinces and territories who build single-family homes and multi-unit residential projects. In day-to-day terms, these are the people pricing out builds, pulling permits, and meeting code requirements — who currently have little visibility into how proposed code changes will affect their costs before those changes are adopted. Suppliers of building materials and products subject to code specification may also be affected, as cost impact summaries could influence whether proposals move forward. The transparency requirements don't impose new compliance costs on businesses directly, but they do give builders and developers a much clearer picture of what's coming down the pipeline, which helps with bidding, planning, and advocacy during the public review period — regardless of whether they're a solo custom builder or a large volume developer.
